Subject Re: Can set different dfs.replication for different dirs
Date Mon, 28 Apr 2014 12:22:25 GMT
Changes the replication factor of a file. -R option is for recursively
increasing the replication factor of files within a directory.

Example:

   -  hadoop fs -setrep -w 3 -R /user/hadoop/dir1

hadoop dfs -setrep -R -w 1 /dir/
